[ng-core] WrappedFormControlSuperclass throws an error on IE11

[DmitryEfimenko]

Reproduction:

• create new Angular project: ng new s-libs-ng12-ie11
• install s-libs and extra polyfills dependencies: npm i @s-libs/js-core @s-libs/micro-dash @s-libs/ng-core @s-libs/rxjs-core classlist.js web-animations-js
• in the polyffills.ts uncomment the imports for classlist.js and web-animations-js
• in the .browserlist enable IE11
• add a component DatetimeLocal (just like in the docs for the WrappedFormControlSuperclass)
• use that component in the AppComponent
• make a production build: npm run build
• start a simple server pointing to serve the dist/[myproject]/
• Open IE11
• Open Developer tools
• Observe an error:

  ERROR TypeError: Object doesn't support property or method 'setUpOuterToInner$'

Side notes

I realize the web ecosystem slowly moves toward the better, brighter future without IE11, but it will still take a while to get there.

According to https://gs.statcounter.com/browser-market-share, IE11 is at 0.71% of global internet usage. Given that, combined with the fact that the Angular team does not set up apps to support it by default, and that I am not set up to run CI on multiple browsers at this point, I unfortunately will say that @s-libs does not support IE11.
